Well, let's see...
Exes - most of them, yes. I think that for the most part, it was other things that led to our breakups - but who's to say?
Wife - she has seen me in a dress or skirt a couple times for a "try on", but doesn't want me doing it around her. Nighties are the limit with her.
I have a close friend who has seen me fully dressed (makeup and all). He says he sees me as both female and male and is my friend either way. He's golden in my book!
I have another one who hasn't seen me dressed, but said something like "You've always been my friend. I can't see this changing that."
Immediate family - I'm really unsure who knows and who doesn't, but I haven't shown anyone my Sara-side. They live a long way away, and the wife-rules prohibit it anyway.
My sister knows. I told her myself, but she hasn't seen me (again, wife-rules). Her comments when I told her "I always wanted a sister."
Strangers - years ago and before current marriage and restrictions, I would go out and mingle a bit. My results were mixed at best.
